Abstract[German]
Die Erfindung betrifft einen permanenterregten Rotor (1) für eine elektrische Maschine (2) umfassend einen Rotorkörper (3) mit einer Vielzahl von Magnettaschen (4) zur Aufnahme von Permanentmagneten (5), welche so konfiguriert sind, dass sie über den Umfang des Rotorkörpers (3) verteilt angeordnete und abwechselnd magnetisch gegensinnige Rotorpole (6) ausbilden, wobei in Umfangsrichtung benachbarte Magnettaschen (4) eines Rotorpols (6) jeweils durch einen sich in radialer Richtung erstreckenden Steg (7) voneinander getrennt sind, wobei in radialer Richtung fluchtend und radial nach außen hin beabstandet von wenigstens einem Steg (7) eine kreisringsegmentartige Öffnung (8) in dem Rotorkörper (3) ausgebildet ist.[English]
The invention relates to a permanent-magnet rotor (1) for an electric machine (2), comprising a rotor body (3) having a plurality of magnet pockets (4) for receiving permanent magnets (5) which are configured to form alternating magnetically opposed rotor poles (6) distributed over the circumference of the rotor body (3), wherein circumferentially adjacent magnet pockets (4) of a rotor pole (6) are each separated from one another by a radially extending bridge (7), wherein an opening (8) in the form of a circular ring segment is formed in the rotor body (3) so as to be radially aligned with and radially outwardly spaced from at least one bridge (7).[French]
L'invention concerne un rotor à aimants permanents (1) pour une machine électrique (2), comprenant un corps de rotor (3) ayant une pluralité de poches d'aimant (4) pour recevoir des aimants permanents (5) qui sont configurés pour former des pôles de rotor (6) magnétiquement opposés alternés répartis sur la circonférence du corps de rotor (3), des poches d'aimant circonférentiellement adjacentes (4) d'un pôle de rotor (6) étant chacune séparées l'une de l'autre par un pont s'étendant radialement (7), une ouverture (8) sous la forme d'un segment de bague circulaire étant formée dans le corps de rotor (3) de manière à être radialement alignée avec au moins un pont (7) et espacée radialement vers l'extérieur de celui-ci.
